spring - 带有 Spring DSL + OSGi 的 Karaf 上的 Apache Camel

Question

我是 OSGI 世界的新手。

版本: Karaf :4.1.0 Camel :2.18.2 Spring :4.3.5_RELEASE_1(Apache 服务混合包)

引用:Camel-UserForum-on same question

我花了很多时间(甚至几天)来搜索/理解带有 osgi 容器的 camel-spring。对于像我这样的初学者，我没有找到适合某些设置或 github..etc 的好文章。

我们的 camel-spring 应用运行良好。现在我们想转移到像 Karaf 这样的 OSGI 环境。我们正在做一些迁移到 OSGI 的工作，我们遇到了一些严重的问题，我们能够解决其中的几个问题，但最终会遇到以下问题:

1. 我不知道在哪里放置 camel-spring xml 上下文和路由文件(以前在带有 NON-OSGi 的类路径中)。所以它没有加载上下文获取找不到文件。

2. 如果我把它写成下面这样，我知道它可能是错误的方式

   ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext( 新字符串[] {“文件:app-camel-spring.xml”});异常(exception):org.springframework.beans.factory.parsing.BeanDefinitionParsingException:配置问题:无法找到 XML 模式命名空间的 Spring NamespaceHandler [http://camel.apache.org/schema/spring]违规资源:URL [file:app-camel-spring.xml]

即使使用 Spring DM 它也不起作用

谢谢，

更新-11. 在论坛要求我查看 GEMINI Blueprint(GB) 后，我现在正在检查 GB。但我仍然遇到与 JAXB 错误相同的错误。

我现在正在使用:菲利克斯:

Answer 1

使用 Apache Karaf 4.0.8，因为 4.1.0 有问题并且不支持该 Camel 版本。

并且 spring XML 文件应该是文件夹中的占位符，如该示例所示，例如 META-INF/spring。

但请注意，Spring DM 已被弃用且已死。因此强烈建议改用 OSGi 蓝图。

在未来，Karaf 将拥有某种 spring XML 到蓝图 XML 自动转换器，因此它可以像运行蓝图一样运行 spring xml 文件。但有关该问题的更多详细信息，请访问 Karaf 社区。
